The board of supervisors of a county may enter into agreements for the lease-purchase of equipment for a period in excess of one year under the following terms and conditions:
1. The lease-purchase agreement shall be executed for the period of one fiscal year only and, if a longer period is needed to complete purchase of the equipment, the board of supervisors shall have the right, at the end of each fiscal year, to enter into an agreement for continuation of the agreement for succeeding one-year periods until complete payment has been made.
2. If, at the end of the first one-year period and prior to payment of the total purchase price, the board of supervisors does not agree to a continuation of the lease-purchase agreement, the seller may repossess the equipment and the agreement shall be deemed terminated.
